According to the characteristics of mini-type sugarcane harvester and optimal crop parameters, the knife was designed with reasonable structures. Consequently, the sugarcane harvester base cutter was designed. The engineering analysis software was employed to accomplish analyzing the structural kinetic, static and dynamic analysis of the knife and the corresponding sugarcane harvester base cutter. Then the structural reliability and crop performance were validated. The natural frequencies of the designed base cutter and its possible destroy forms were also attained, which provided some references for sugarcane harvester designing. The 3-D model software was applied to plot the 3-D model of the base cutter. It can be used for the exploitation of the physical prototype for further applications. 
